TWIS'IER RING.

To all w/zom 'a'z .uwy concern:

Be it known that I, 11L110 A. Kosnnn, a citizen of the Republic ofFinland, residing at New York, in the county of New York and State ofNew York, have invented new and useful Improvements in Twister Rings, ofwhich the following is a specification.

This invention relates to twister rings of that type wherein the ringtravelers are of substantial weight and are mounted in roller bcaringsin series on a rail.

One of the objects of this invention is to provide a construction whereas large traveler rings may be employed may have running clearancebetween each other. Cops or bobbins wound to comparatively large size sothat replenishment is less often necessary may then be used inconnection with the twisting mechanism.

A. further feature of the invention relates to the manner of supportingeach traveler on four rollers, the number of bearings de creasing thewear over a construction wherein fewer are employed. By utilizing allthe rollers possible to support two traveler rings, each of the travelerrings may have a four roller support and yet the whole series employsonly two more than twice the number of travelers.

A. further feature relates to lubrication of the various traveler rings,any excess oil draining into a trough at one side of the rail where itmay be readily removed.

Another feature of the invention relates to means for preventing theyarns from adjacent bobbins from becoming entangled due to the closespacing of the travelers.

Yet another feature resides in a construction wherein theroller-carrying brackets are integral with the rail.

Further features and advantageous details and combinations of parts willappear from a description of certain embodiments thereof shown in theaccompanying drawingsin which- Figure 1 is a fragmentary plan of a railshowing 'a plurality of traveler rings in position thereon.

Figure 5 is a section on line 5 ure 1. i

Figure 5 is a fragmentary plan showing a modification.

Figure 7 is a section on line 7--7 of Figure 6. Referring first to theconstruction shown in Figures 1, 2, 3, and 5, 1 indicates the rail forsupporting the ring travelers. As shown this rail comprises a castinghaving a series of perforated bosses spaced therealong as shown at 2above which are positioned the ring travelers as will be described.Between adjacent pairs of bosses 2 and closer to the side edges of therail, are other bosses 3 which are centrally perforated as at i for apurpose which will later appear. At one end of the rail is shown a pairof bosses 5 to which are adapted to be made fast brackets or casings 6,as shown in Figure l, which house small end bearing rollers 7 which, aswill. be later described, help to support the end traveler rings of theseries. At one edge of the rail is formed a trough shaped portion 10 andthe upper surface of the rail between the various bosses slopes from theopposite side edge of the rail downwardly toward the trough 10 so thatany oil which finds its way to the top surface of the rail is directeddown to the trough where accumulations thereof may be removed by wipingthe trough out as with cotton waste at intervals. The bosses 6 arrangedadjacent the trough 10 are providedwith extensions 12 providing verticalwalls 13 extending upwardly from the inner edge of the trough. Thebosses 3 along the opposite side of the rail are extended to the edgethereof as shown at 14; which edge has a downwardly extending flange 15thereon. Bracket mem bers 16 provided withdownturned ends 17 bridgeacross the width of the rail, the portions 17 engaging at one sideoutwardly of the flange 15 and at the other side against the surfaces 13andbeingfixed thereto as by bolts. These brackets therefore bridge therail at spaced pointsulengthwise thereof above the bosses 3 and betweenthe bosses 2. The intermediate portions of the brackets 16 are spacedabove the rail, and above the perforations 4; therein they are providedwith perforated bosses 18 in which may be fixed journal pins or. shafts19. These pins are somewhat smaller in diameter than the 5 ofFigperforations in the bosses to permit of adjustment therein and areheld in proper position by means of washers 20 and shoulders 20overlapping the upper and lower ing into this space.

faces, respectively, of the bosses 18 and which are clamped thereagainstby means of nuts 21 threaded on the upper ends of the pivots. bracketsare supported on the upper faces of flanged bearing rollers 25 which arejournaled on the pins 19. As shown these bearing rollers each havedepending bearing sockets 26 within which the pins 19 extend, thesesockets 26 extending well into the perforation l of the rail bosses 3.At the periphery of each roller is formed a downwardly extending sleeveportion 250 concentric with and spaced from the outer face of the socketportion 26 this portion carrying upper and lower flanges 251. Thispermits a cup shaped member containing lubricant as at 27 to be heldwithin each perforation t with its upper edge eXtend- As shown the cup27 is provided with an outwardly extending bead 28 adjacent its upperend by which it is supported by the edge of the perfora tion 4.Lubricant in these cups is permitted to reach the bearing between thepins 19 and the sockets 26 through openings 2 laterally of thesesockets.

Positioned between the flanges 251 of the rollers and supported forrotation thereby are the ring travelers shown at 30. It will be notedthat these travelers, which are positioned between adjacent brackets 16,are supported entirely by the four rollers journaled therein while theend ring travelers of the series are supported by the rollers of the endbrackets 16 and the rollers 7 positioned at the ends of the rails. Thering travelers are supported above the perforations through the bosses 2and con centrically therewith, the perforations through these bosses, asshown, being of slightly less diameter than the central opening of thering. Each ring, as shown. is

provided with a yarn eye 31 through which the yarn passes from the usualcop or bob bin (not shown) positioned below the rail in axial alinementwith the ring travelers. As the strand passes up through the openmg andis rotated when the mechanism is in operation, it balloons outwardly dueto the centrifugal force resulting from its rotation. As theadjacentrings are so close 'ogether since their outer peripheries almosttouch, this effect if permitted would tend to cause interference betweenthe strands acted upon by adjacent rings. For preventing any such actioneach bracket 16 is shown as having a fin 35 projecting upwardlytherefrom between its pivot pins 19: these fins forming partitions orbarriers to confine the strands from the travelers with- The washers 2Obeneath the in proper limits to prevent encroaching on the paths of thestrands of adjacent rings.

For the purpose of applying lubricant to the travelers as well as toprovide a retarding action to their too free rotation, wiping pads maybe employed. such pads being shown at 35 in Figures 1 and beingpreferably made of felt and each partially enclosed within a channelshaped head 3? carried at the end of a leaf spring 38. This leaf springas shown is supported midway of its length on the reduced extremity ofan adjustable pin 40 passing through one portion 1? of a bracket 16. Acoil spring 4-1 surroumling a larger portion of the pin 40 bears at oneend against a head 42 hereon, which is threaded into the bracket 16 andat its other end against one ace of the spring The head9 7 may have anopening 41-5 formed therein through which oil may be introduced intocontact with the felt 36 so as to be transmitted thereby to theiieriphery of the ring traveler. this in turn being engaged by therollers 25 in the adjacent bracket 16 transferring the oil to the nexadjacent ring traveler and so on through the entire set of travelers. Asshown the wipers are arranged in pairs at either end of a spring 38 sothat the need be supported only at each alternate bracket 16 throughoutthe length of the rail.

With this construction it is seen that each ring traveler is supportedby four rollers, each. of the rollers carried by the bracket 16 servingto support two travelers, whereby the total number of rollers is twomore than twice the number of ring travelers, these two additional beingdue to the end rollers 7 each of which engages only one traveler. As thebrackets 16 bridge across the rail the ring travelers may be ofsulliciently large diameter to pass under each bracket it beingnecessary only that the travelers should be sufficiently small to avoidactual contact in running. By employing such large travelers the windingsize of the cop or bobbin may be large so that necessity ofreplenishment is rendered less frequent, thus saving time and labor inthe operation of the machine. Any excess oil above that required toproperly lubricate the travelers tinds its way down the inclined face ofthe rail to the trough 10 where it may be removed from time to time byrunning a piece of waste along the inner surface of the trough. By thismeans accumulation of oil which might soil the work is provided.

In Figure 4: a modification has been shown in which instead of formingthe brackets 16 separate from the rail and fastening thereto as by meansof the bolts shown, the brackets may be made integra with the rail. Whenthis is done, in order llO tion.

to be able to properly assemble the parts, it is preferable to form thebosses 3' of the rail above which the rollers are mounted su'tiicientlylarge in diameter to permit the perforation l therethrough to beslightly greater in diameter than the diameter of the roller. The rollermay then be inserted therethrough into position on the shaft 19 as shownin Figure 4L and the oil cup 27 may be formed with its lower portion o'lsufliciently large diameter to tit snugly within the hole l and itsupper end reduced as shown at 27 to pass within the passage 27 of theroller. These oil cups may be held in position within the openings l byany suitable means such as leaf springs 50 made last to the lower faceof the rail and engaging the lower faces of the cups. As the bosses 3"must be considerably larger than the bosses 3 shown in Figure 2, it maybe necessary to cutaway a portion of these bosses or the bosses 2 topermit passageways for the oil down the inclined upper face of the rail.

In Figures 6 and 7 is shown a further modification, this modificationresiding in the construction of the end rollers and supports which acton the end rings only. In place of the rollers 7 shown in Figure l apair otrollers 52 and 53 are shown which are journaled on stub axles 54:fixed to a bracket 5 upstanding from the face of the rail. These rollers52 and 53 are spaced apart suflioiently to: permit the ring traveler 30to pass therebetween and one of the rollers herein shown, as roller 53,is provided with an end. flange 56 to engage the outer vertical face ofthe ring. As shown the lower roller 53 may dip into alubricantcontaining cup 57 supported on a portion of the rail so thatlubricant may be picked up from the cup and transferred to the ringtraveler. It will be noted that in this form of the device the rollersengaging the ring are journaled on horizontal axes while the ringtraveler rotates about a vertical axis and that this constructionpermits the end rollers to be used to convey lubricant to the endtraveler rings and thus tothe entire number of traveler rings.

Having thus described certain embodiments of this invention, it shouldbe evident to those skilled in the art that many changes andmodifications might be made therein without departing from its spirit orscope as defined by the appended claims.
